haproxy并发请求的问题? 400 报错
haproxy并发请求的问题? 400 报错
发现haproxy当后端收到请求没有没有返回应答前，前端收到的第二个请求不会发送到后端。
结果就是前端收到的请求全部串行发送到后端。
是否有相关设置解决该问题？
配置文件

daemon
maxconn 256
defaults
mode http
timeout connect 5000
timeout client 50000

A last improvement in the communications is the pipelining mode. It still uses
keep-alive, but the client does not wait for the first response to send the
second request. This is useful for fetching large number of images composing a
page :[CON] [REQ1] [REQ2] ... [RESP1] [RESP2] [CLO] ...
This can obviously have a tremendous benefit on performance because the network
latency is eliminated between subsequent requests. Many HTTP agents do not
correctly support pipelining since there is no way to associate a response with
the corresponding request in HTTP. For this reason, it is mandatory for the
server to reply in the exact same order as the requests were received.但是不知道怎么配置才能达到这个效果
